PGA400-Q1EVM程序下不进，小白求解释，谢谢。

如题，下载hex文件出现如下报错：

小白求解释，多谢了。

要怎么设置才可以，多谢。。。

是不是没连上或者电没有供上,读回来全是0

供电正常，四个LED全亮。

你的测试环境是什么样子的？你提供的信息太少，从你的提示来看，是EEPROM通信问题。

这个是硬件连接，如图。

这个是上位机软件，初始设置，没有配置。求解。

请按照EVM user's guide 中的给出步骤进行操作，参考page24 “6.6.1 Load .HEX File into GUI” 部分，看在哪个环节出现了问题 http://www.ti.com/lit/ug/sldu010/sldu010.pdf

+5V稳压芯片貌似被烧掉了，整板供电已经成了+7.5V。。。

Hi Song Zhao,

请问，您现在PGA400的评估，进展如何了？

请检查整板供电是否正确？另外所选用PGA400GUI的版本号。

还有问题，请联系我处
